Rock band the Foo Fighters are suing insurers for failing to reimburse them for shows they cancelled in the wake of the Paris terrorist attacks in November.
The lawsuit filled on Monday alleges that the US rockers are owed for gigs they called off in Turin, Paris, Lyon, and Barcelona.
The band said the website, www.foofighterstours2015.com, had been hacked the day after the attacks to display a so-called Islamic State flag, automatic weapon and the threat "be prepared".
Following the terror attacks which left 130 dead, so-called Islamic State also released a video threatening additional attacks in Europe.
The lawsuit is against underwriters Lloyd's of London and the insurance broker responsible for securing the policies, Robertson Taylor,
The band says it believed it will be paid for the Paris and Lyon cancellations, but alleges that Robertson Taylor advised underwriters against paying for the other two cancelled shows.
The Foo Fighters are also suing the insurers for three shows which the band were forced to cancel after frontman Dave Grohl fell off the stage and broke his leg while performing in Sweden last summer.
